Abstract

This paper presents two applications of Fiber Optic Refractive Index measurements for Chemical Processing. The first one has been developed at IFP Solaize in France and is aimed at providing concentration and mixing efficiencies measurements inside catalytic beds. The second one, developed at several oil processing plants in the USA provides end point monitoring of the food oil hydrogenation process. Both applications use the Metricor2000 system, which provides accurate refractive index measurements (down to 0.0001), using white light interferometry and Fabry Perot sensing cavities. The applications will be described and experimental results provided.
